Here is a mini adapter, maybe you could squeeze them in with it, about 1 cm

Thank you for the tip. This adapters have half the height of regular ones, and my tubes are 2-3mm over rim of the cover, they will definitely work.

I should have known better than to buy 2 singles of JW WE396A's. The first one came yesterday, looking and sounding good. The 2nd, not so much. It has a fairly loud pulsating hum.

First bad tube in over 50 tube purchases. Maybe I was just due.

Okay, I have been listening to to the Tung Sol 2C51 tubes some more. They are starting to come around. I will give them more time, another 80 hours or so, before I make a final comparison to the WE tubes..

 

[roman410]

My JW 2C51 tubes arrived today, with date codes 839 and 852, indicated they was made in 1948. What I was noticed first, printing paint on this tubes it's so thick, like 3-D when I go over with my finger. I never see before something like just this. It is that normal?

Also printing missing 396A tube type. Most of this JW tubes sold on ebay have both 2C51 and 396A printings. It is certain date when Wester electric add 396A prints to this type of tubes?

Can somebody please school me on the Tung-Sol 2C51 differences between D-getter vs O-getter vs JTL versions.

Thanks. I will hang up and listen.

Yes, print/paint is thick, durable.
JW is the military designation and 2C51 is the broader industry tube type. 396A is specific to WE, ATT, Bell Telephone. WE literature states that 2C51 and 396A are identical. Link to literature is probably included a few pages back.

One, if not all, of my WEs from the late 40s has that same, thick yellow paint, so I wouldn't sweat it. Haven't heard about anyone counterfeiting 2C51s yet, but I've got Rangy working on it

Can't answer question #2.

Big thank you to @rnros for sending me a pair of adapters for free, come in 1 day bro!
20 hours in with the TS 2C51 square getters and sound better now, not as rich as the JW`s but probably better dynamically. Highly detailed as well, going to give it a 100 and chuck the next set in. My 3rd pair just came in as well, they look like they got some hours on em, no noise, or microphonics.

Just throwing it out there, anybody in the USA looking to trade? I got 3 pair and would be willing to trade a pair of TS`s for a pair of Bendix 5670? Either 1 new pair or the used pair I got from China for $60. All no noise or microphonics.

That distinctive bass starting to come through yet TK ?

 

[TK16]

Still got a ways to burn in it seems, much better than last night for sure. Phenominal midrange for sure. Got a lot of untapped goodness in it for sure.

You guys noticing these tiny tubes burning in quicker than regular 6DJ8 variants?

 

[billerb1]

Computer blowed up. It blowed up real good. Probably a week till I get it back.
Sammy could have saved me. He didn't.
I may have to change my signature.

In case anyone is befuddled by the lack of information on this Ebay listing: http://www.ebay.com/itm/NOS-Pair-TungSol-2C51-Black-Plate-Twin-Triode-Vacuum-Tubes/151621028745?ssPageName=STRK:MEBIDX:IT&_trksid=p2055119.m1438.l2649

Seller told me that he received this set of tubes from the Mexican military. I was told 1 in 10 of the tubes maintained some of the Tung Sol branding. I requested a tube that has the branding (maybe one of the last). Seller is unaware of the year of manufacture, no date codes available, but based on the presence of D-getters, guesses late 50's.

Here is what I received:



Other than the poor print (any tubes ordered likely won't have any print at all) the tubes look to be brand new and 100% legit. Sound great, have some microphonics on tap. I know that is a thing, but what is the concern with microphonics on tap?

Edit: At the time of this post, I didn't understand what microphonics were, these are fine, just your normal glass "ting" on tap, no microphonics.
